I found this ad digitized by Google Books in a 1907 edition of American Blacksmith Magazine. So Buffalo Forge, at this time, was making more than forges. And, like Canedy-Otto, they also made drills. According to Knight's American Mechanical Dictionary (1882 edition, also found digitized on Google Books), a tire upsetter is "a machine for shrinking tires without cutting. A tire is heated and then forcibly compressed endwise, so as to thicken it in one part and shorten it. It is then, while yet hot, placed on the wheel and shrunk in position." Where was American Blacksmith published? In Buffalo's famous Prudential Building, designed by Louis Sullivan and Dankmar Adler.
